Following the Brooklyn Nets’ embarrassing 95-78 Christmas Day loss to the Chicago Bulls, an exasperated Jason Kidd called his players out in the locker room, according to multiple league sources.

Tired and upset with a lack of effort, Kidd’s outburst came after the Nets dropped their fourth straight game, sources say. The first-year head coach said Monday after a 103-86 loss to Indiana that the Nets were becoming too comfortable with losing.

The frustration is mounting. According to league sources, after Kidd yelled at the team on Wednesday, Kevin Garnett stood up and vented his frustration before walking out to the showers. Multiple sources stressed Garnett backs Kidd and that the veteran’s frustration has been building over some of his teammates’ lack of fight after the Nets lost by 17 points for the second straight game.

Sources also said Garnett’s walking out was viewed as him being one of the few Nets to care about the team’s downward spiral. […]

Multiple league sources told Youngmisuk that Kidd was tired and frustrated with the team’s lack of effort following their fourth straight loss. This came after Kidd said the Nets were “becoming comfortable with losing” on Monday night after another embarrassing loss, that one to the Indiana Pacers.
